price 12s.; for collecting and preserving only, Greene’s 
‘Insect Hunter’s Companion,’ price ls. 6d. There are a great 
many others, but they are either profound and learned books, 
unintelligible to beginners, or pleasant compilations by authors 
who have little or no practical acquaintance with the subject. 
The above three books are published by Mr. Van Voorst, and 
have been prepared especially to supply a want felt by all 
learners.— Hdward Newman. | 
C. Le Merle Adams.—Palpi (or feelers)—organs attached 
to the jaws of insects; ciliated—fringed with a series of 
paralle] hairs; pectinated—furnished on one side with a 
number of stiff parallel branches resembling the teeth of a 
comb; costal—near or on the upper edge of the wing; 
reniform—kidney-shaped ; discoidai—in the middle of the 
wing, not near its margin; orbicular—round; glabrous— 
smooth and shining; dorsal—on the back or upper surface ; 
tsabelline—the colour of a fawn; Jateral—on the side; 
reticulations—fine marks like net-work. For explanations of 
this kind I may also refer to the books recommended in 
the previous note. There is no English work containing 
illustrations of most of the Lepidopterous larve.—Edward 
Newman. 
Thomas Eedle and others.—I believe the nests sent this 
summer from Scotland to be those of Vespa sylvestris of 
Scopoli (Sp. Insectorum,’ vol.i.p.460). I have particularly 
examined the series of perfect insects, males and workers, 
just brought by Mr. Eedle on his return from Rannoch. 
Entomologists, who are desirous of studying the species of 
British wasps, would do well to take the entire nest and all 
its contents, and, after having allowed the cyanide to do its 
work, to set and preserve every specimen, labelling them and 
their nests with a similar number, and not introducing a 
single specimen that was not actually killed 7m the nest. 
Mr. F. Smith, of the British Museum, and subsequently 
Dr. Ormerod, of Brighton, have laboured industriously to_ 
make the species intelligible: the discriminative remarks of 
the former, and the figures of the last-named author, are most 
praiseworthy. ‘I'he difficulty of the subject, however, is very 
manifest, from the conflicting synonymy in Mr. Smith’s own 
various papers. An unmistakable figure of the nest of this 
wasp will be found on plate vi. of Dr. Ormerod’s ‘ British
